Actually you don't need to. This layer of clustering has been abstracted from the administrator as it used to cause confusion for some administrators in Windows Server 2003 server clusters. Now this is managed entirely by the cluster service. If you shut down the node that contains the quorum disk (if you're using that mode), it will automatically be moved to another node.It's not something you need to deal with any more.
